Imaging results suggest that the echogenicity of the uterine cavity is uneven, which can be seen in physiological conditions and pathological conditions, generally refers to the state of endometrial repair in the uterus, or the presence of residual tissue, fluid accumulation and other conditions. 1. Physiological conditions: generally appear in the process of endometrial repair after the end of menstruation, or in the process of endometrial repair after childbirth. 2. Pathological condition: It may be caused by the damage of the endometrium, the adhesion of the uterine cavity, or due to the endometrial pathology, such as endometrial hyperplasia, polyps, and so on. Therefore, when the imaging test suggests that the echogenicity of the uterine cavity is uneven, women need to pay attention to differentiate the time of the examination, and if it is a physiological cause, there is no need to worry too much. If the cause is pathologic, it is recommended to consult a doctor for ultrasound, hysteroscopy and other related examinations to avoid delaying the condition.
